As the NO.1 ROM provider in the industry, we continue to offer the cutting-edge ROM products to our valued customers. Migrating from Mask ROM to XtraROM® with significant resources investment, Macronix has made ROM products more flexible in production and delivery, while preserving high quality and cost advantages.


Macronix excels at customized XtraROM® from IC design to content programming with short TAT (Turn Around Time) and quick delivery. The host MCU of XtraROM® solely must READ the contents; it need not worry about bad blocks, wear leveling, and ECC. With no extra mask charge, we can also build your DRM (Digital Right Management) scheme in the circuit of XtraROM® to protect your content from being pirated. Our designs are used as robust medium for content publishing in gaming applications around the world.
